American fourth seed Jessica Pegula reached her first Wimbledon quarter-final with a dominant display against Ukrainian Lesia Tsurenko.
Pegula won the first five games on her way to a 6-1 6-3 victory over the world number 60.
Tsurenko had spent nearly three hours longer than Pegula on court over the past week and that seemed to take its toll in an error-prone display.
Pegula will face 2019 French Open finalist Marketa Vondrousova next.
Vondrousova beat fellow Czech Marie Bouzkova 2-6 6-4 6-3 earlier on Sunday.
Wimbledon was still playing catch-up with the schedule after a rain-disrupted week, with Russian 16-year-old Mirra Andreeva winning her third-round encounter against compatriot Anastasia Potapova to advance to a last-16 meeting with American 25th seed Madison Keys.
